Before I start, I would like to say that I'm quite a newbie to Xcode and the C Language, and I'm trying my best to learn as much as I can. I have researched for about 2 days now before posting this question but could not find anything helpful :( I am genuinely stuck and would appreciate ANY help. This is most likely a very simple/basic question:
Basically, I am trying to get this data (LINK) which is apparrently in UTF-8 JSON and display it on a simple label on Xcode. However, I do not know how to get that data and parse it at all. I've followed a tutorial online with success, but that deals with JSON objects rather than arrays (which I think I am dealing with).
I would HIGHLY appreciate it if someone could extract/parse the data from the first link given into a basic label on Xcode in code format.Preferably with commentary on what most lines of code are doing for my own benefit, as this would really help me understand how it works. Hopefully from there, I would be able to make good progress.
Once again this is highly appreciated!
Thank YOu.
Here's a sample of the JSON URL for convenience if you don't want to click the link:
[4,"1.0",1343920773538]
[1,"Spring Gardens","59581","275","Barkingside",1343920940000,1343920940000]
[1,"Spring Gardens","59581","275","Barkingside",1343921717000,1343921717000]
[1,"Spring Gardens","59581","549","Loughton",1343921858000,1343921858000]
[1,"Spring Gardens","59581","275","Barkingside",1343922204000,1343922204000]
[2,"Spring Gardens","59581","8a56a0ab37b72b400137cb7cfd954038_29222",0,3,"Bus routes serving this stop are subject to change during the Olympics and Paralympics games. For more information visit www.tfl.gov.uk/buses for more information.",1344668400000]
Use JSONObject like that tutorial shows, you should get a NSDictionary or NSArray at the end which will contain all your values just map those to the label in the end.
If you dont wan to do that, save the response in a char array and navigate through it while checking for [ or " characters when you find one read the chars until the next occurrence and save all the data you read into an array or something but this is messy and involves atleast 3-4 hours of writing your own custom logic for JSON data decryption, you should use JSONObject which is pretty simple
Hi i have this same problem. I have been looking for a json solution and currently i found that the best way to deal with this data is to parse is as csv instead. The solution seems straight up when you try to parse it as CSV instead of JSON

Here's what I'm doing:
=IMPORTXML("https://www.predictit.org/api/marketdata/markets/7164", "/MarketData/Contracts/MarketContract/ID")
The other answers I've seen about this have said that Javascript would be the issue, but the page in question seems to load without it, and I've tried using IMPORTJSON and IMPORTFROMWEB to no avail.
Please help!
You are input incorrect parameter for the xmlpath, a proper formula should be as following and you need to spend sometime to find the correct xmlpath to extract the specific string or information you want,
=IMPORTXML("https://www.predictit.org/api/marketdata/markets/7164","//a/#href")
Here is one example from Google:
=IMPORTXML("https://en.wikipedia.org/wiki/Moon_landing", "//a/#href")
I have downloaded from PocketApp (Loading Json Data) from Github as per link: https://github.com/vaibhavgupta06/PocketApp-Test.
But the link to retrieve JSON database was gone already.

Could anyone help me find the JSON file for me.
Thank you very much.
It is pretty easy to infer the schema based on the code. It is an array of books with an author property. I wrote the schema here: https://gist.github.com/jonathanRose/87d70449a3a1df3f1bae1f6d6d4a7971
and an exampled based on it here:

good luck.
I'm honestly stumped as to how I could do this. I've been searching and trying out different methods for the past day or so and none have worked. What I'm basically trying to do is store comments for a post (Each row represents a post). I've been reading through the Parse documentation and have tried to implement some of the things that they have there into my code in order to achieve this, but that hasn't worked out either. If anybody could help me out, I'd be extremely greatful.
This exact task is the example provided in the documentation.
http://docs.parseplatform.org/ios/guide/#relational-data
You need to create a new class called "Comments" and then refrence its parent post as one of it's columns.
Hey guys this has been tripping me up quite a bit. So here is the general problem:
I am writing an application that requires users to enter their Summoner Names from league of legends. I do a pretty simple data scrape of a match and enter the data into my database. Unfortunately I am having some errors registering users with "special characters".
For this example I will use one problem user: RIÇK
As you can see RICK != RIÇK. So when I do the data scrub from the site I get the correct value which I push onto an array for later use.
Once I need the player names I pull from the array as follows: (player_names is the array)
#temp_player = User.find_by_username(player_names[i].to_s)
The problem is the users with any special characters are not being pulled. Should I not be using find_by? Is to_s changing my original values? I am really quite lost on what to do and would greatly appreciate any help / advice.
Thanks in advance,
Dan
I would like to thank Brian Kung for the link to the following: joelonsoftware.com/articles/Unicode.html It does a great job giving the bare minimum a programmer truly needs to understand.
For my particular issue I had used a HTML scraper to get the contents but which kept HTML entries throughout. When using these with my SQL lookups it was obvious that things were not being found. In order to fix this I used the HTMLEntities Gem to decode the text as follows (as soon as I put the into the array originally):
requires 'RubyGems' #without this cannot include htmlentries as a gem
requires 'HTMLEntries'
coder = HTMLEntries.new
line = '<'
player_names.push(coder.decode(line))
The Takeaway
When working with text and if running into errors I would strongly recommend tracing the strings you are working with to the origin and truly understanding what encoding is being used in each process. By doing this you can easily find where things are going wrong.
Using NSXMLDocument, without using XPath, is there an easy way to parse an XML document and deserialize it into custom objects to create an object tree hierarchy?
For example, if I have the xml shown below, is it possible to put the details into a Restaurant object and a content object within it?
<restaurants>
<content>spanish name</content>
<content>english name</content>
</restaurant>
<spa>
<content>spa spanish name</content>
<content>spa english name</content>
</spa>
I will be using your answer above to extend it for programming in kissxml in iOS. As the kissXML document mentions that the XML parser behaves in the same way as NSXMLDocument, so I've asked the question using NSXMLDocument.
If you know your expected content structure, the easiest is to just use NXMLParser and loop through it looking for the bits you need and keeping track of the previous bit, building an object as you find them.
If you want tree-based approach, consider learning XQuery and XPath, they are not all that bad. Without them, the only thing NSXMLDocument really gives you is Cocoa bindings.
At the end of the day you must transform your data somehow.
With NSXMLDocument you will still do well to validate against an XML DTD if possible, to ensure you have good data.
With NSXMLParser, you are able to handle things without a formal DTD.
You only need worry about how big the data is, an how you want to parse it, then do some trial and error with test data to ensure it's grabbing what you want or need.
